I would like you to tell me what could be achieved with your suitable device.

I would to sample every 15 minutes but if posible on state change.

The application is to record 5 inputs changing state in real time allowing us to calibrate in a display, the logging time could be 7 days we would like it to be longer.

Hi with reference to the picolog is it posible to record data without a pc connected or is this unit only able to stream data, do you have a logging device that could store the data for upload at a later date.
